Calculate how much power a tractor engine can develop, which moves evenly along a straight road, if the traction force is 1, 2 kN and the distance traveled by it in an hour is 3.6 km
F = 1.2 kN = 1200 N.
S = 3.6 km = 3600 m.
t = 1 h = 3600 s.
N -?
Tractor power N shows the speed of performing mechanical work A and is determined by the formula: N = A / t, where t is the time of work.
The mechanical work of the tractor A during movement is determined by the formula: A = F * S, where F is the traction force of the tractor engine, S is the movement of the tractor.
The formula for the tractor power will take the form: N = F * S / t.
N = 1200 N * 3600 m / 3600 s = 1200 W.
Answer: the tractor power while driving is N = 1200 W.
